Compares each value within the numeric array with another value.

and rhs
The behavior is undefined if size() != v.size()
lhsv
and the corresponding value of rhs
.lhs
and rhsv
.

[edit] Parameters
lhs, rhs | - | numeric arrays to compare |
lhsv, rhsv | - | values to compare to each element within a numeric array |
[edit] Return value
A numeric array of bool containing comparison results of corresponding elements.
[edit] Exceptions
(none)
[edit] Notes
Each of the operators can only be instantiated if the following requirements are met:
-
- The indicated operator can be applied to type
T
- The result value can be unambiguously converted to
bool
.
- The indicated operator can be applied to type
The function can be implemented with the return type different from std::valarray. In this case, the replacement type has the following properties:
-
- All const member functions of std::valarray are provided.
- std::valarray, std::slice_array, std::gslice_array, std::mask_array and std::indirect_array can be constructed from the replacement type.
- All functions accepting a arguments of type const std::valarray& should also accept the replacement type.
- All functions accepting two arguments of type const std::valarray& should accept every combination of const std::valarray& and the replacement type.
- The return type does not add more than two levels of template nesting over the most deeply-nested argument type.
